17 wrz 2018 · Helicobacter pylori is a Gram-negative, microaerophilic bacterium colonising the gastric mucosa. Normally, this bacterium has a spiral shape, which is crucial for proper colonisation of the stomach and cork-screwing penetration of dense mucin covering this organ.

H. pylori, a dominant human pathogen, is now recognized as the first member of an ultrastructurally diverse genus. The predominant morphological form of this genus is curved to spiral; however, some members have either a short or tapered rod shape. All helicobacters are motile by means of flagella.
24 sie 2022 · Recent work characterizing cell shape mutants of Helicobacter pylori revealed a novel mechanism for the generation of a twisted helix from a rod, including PG-modifying enzymes as well as additional proteins such as the bactofilin homolog CcmA or the membrane proteins Csd5 and Csd7.
Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, flagellated, helical bacterium. Mutants can have a rod or curved rod shape, that exhibit less virulence.
The helical Helicobacter pylori relies on its unique shape for survival and efficient colonization of the human stomach. Yet, they have been observed to transform into another distinctive morphology, the spherical coccoid.
Bacterial cell shape is largely dictated by peptidoglycan (PGN) or cell wall; a heteropolymer consisted of glycan chains cross-linked together by peptide stems (Vollmer et al., 2008).
Helicobacter pylori is a Gram-negative, microaerophilic bacterium colonising the gastric mucosa. Normally, this bacterium has a spiral shape, which is crucial for proper colonisation of the stomach and cork-screwing penetration of dense mucin covering this organ.
